a bracket 18 on the breast-beam. WVhen this magnet is excited and draws down the armature and its lever against the supporting spring 19 of said lever 17, it will put the end of said lever in the path of the nose l6 on thelever 16, and at the next beating-up movement of the lay 2 this nose 16 will impinge upon the end of the armature-lever 17, and as the lay continues to move forward the movement of the shorter arm of the lever 16 will be arrested; but the fulcrum y will continue to move forward,th us causing the longer arm of the lever to press forward the springarm 11, and this latter will carry the section lOof the shuttle-box to the position seen in Fig. 1. When the lay-head 2 swings outward again, the section 10 of the shuttle-box will close in, carrying the shuttle with it to the position seen in Fig. 1, the slide 13 again closing the bottom of the magazine.

The electrical controlling devices whereby the electromagnet M is excited when the bobbin or cop in the shuttle in the loom shall have been denuded or nearly denuded of weft or filling will now be described with especial reference to Figs. 6, 7, and 8.

The shuttle 8 in the form herein shown contains a spindle 20, hinged at its larger end in the shuttle in a known way, and on this spindle is slipped a cop or butt-cop. Cops and butt-cops are well known; but the buttcop 21 herein shown is specially constructed in some respects for effecting circuit connections or closures, and these features will now be described. On the spindle 20 is a loose metal ring or conical annulus 22, backed by a spring 23, and fixed on the spindle is a stopcollar 24: to limit the movement of said ring 22 when the spindle is empty. This ring 22. is connected electrically by a conductor 25, Fig. 7, with a piece or plate of metal 26, set in the outer face of the shuttle at its side. The butt-cop 21, carrying the weft, is slipped onto the spindle, as seen in Figs. 6 and 7. It has on its larger part a metal ring 28, connected by a metal strip or wire 29 with a metal It has also set in its end a piece or ring 31, of metal, which is pressed into contact withthe conicalannulus 22 on the spindle. The piece 31 is insulated from the ring 28 and has attached to ita metal spring 32, which plays in a slot in the cop, and its free end takes un der or within the ferrule 30 thereon at the slot. A part 32 of the spring 32 projects out from the slot in the butt-cop, and this exposed portion is overwrapped by the weftthread in Winding the cop, so as to put the contact-spring 32' under a slight tension and keep its free end pressed away from the in- In Fig. 6 a little ner face of the ferrule 30. of the weft v is shown as wrapped over the spring 32 at 32 and holding said spring pressed in. The ring or band 28 is adapted to form an electrical contact with a piece or rod of metal 33 in the shuttle when the hinged spindle bearing the cop is pressed down into the shuttle. As here shown, there is a circumferential groove in the ring or band 28, and this is engaged by the piece 33, which is in the form of a cross-rod or stiff wire. The contact-piece 33 is electrically connected by a conductor 3% in the shuttle with a piece or plate of metal 2.6 set in the outer face of the shuttle at its side and forming with the piece or plate 26 what may be called the circuitterminals of the shuttle. In Fig. 6, owing to the nature of the figure, the conductors 25 and 34 are represented diagrammatically. The conductor 25 may be conveniently formed integrally with the spring 23.

By following the construction above described it will be seen that the plate 26 is connected electrically with the spring 32 through the conductor 25, spring 23, sliding annulus 30 through the conductor 34, the contact rod or piece 33, the ring or band 28, and the conductor 29. Thus if the free end of the spring 32 is allowed to come into contact with the ferrule 30 by the denudation of the cop the electric circuit will be completed between the plates 26 and 26 Referring now to Fig. 8 particularly, which shows the shuttle driven into'the shuttle-box by the picker, it will be seen that in the side 1O of the shuttle-box are two apertures 35 and 35 which are found opposite to the respective plates 26 and 26 on the shuttle in the box, and on the'box-side 10 adjacent to these apertures, are mounted contact-terminal springs 36 and 36 which bear on the respective plates 26 and 26 of the shuttle. These contact-springs form terminals of an electric circuit to, including any suitable generator G and the coils of the electromagnet M. The weft or filling on the cop or bobbin will, as before stated, break the electric circuit, or hold it open, between the ferrule 30 and spring 32 until the weft is wholly or nearly exhausted, only a little of it remaining on the butt-cop back of the point 32 When the cop is thus denuded, the spring 32 will spring outward and close the break between it and the ferrule. When this is the case and the shuttle is driven into its boX, the circuit will be completed at the plates 26 and 26 and the magnet M excited. This will place the armature-lever 17 in the path of IIO the nose 16 on the lever 16, and at the next beating-u p movement of the lay the exhausted shuttle will be discharged and a filled one taken in from the magazine, as before explained.

Referring now'to Fig. 1, it will be noted that a part of one side or face of the magazine 7 is hinged like a door and held closed bya spring. This is to hold back the upper shuttles 8 and allow the lower one to fall out freely. 7 is a part or section of one side of the magazine, hinged to the fixed part at its upper edgeand held up in place by aspring 7-.

The lower portion of this hinged section is cut away on the inner face at 7* to allow easementorlooseness of the lower shuttle. When the slide13 moves in to theposition seen in Fig. 1, its end strikes and pushes out the lower.

end of the section 7 of the magazine a very little, thus allowing the shuttles in the magazine to settle down by gravity; but when the moving section 10 of the shuttle-boxdrives back the slide 13 the spring 7 causes the upper part of the section 7 to press firmly upon and clamp the shuttle next above the bottom one and hold it and those above it from descending, thus leaving the bottom shuttle free to fall into the shuttle-box section 10.

Figs. 3 and 4 do not show the shuttle-magazine 7. They are designed, mainly, to illustrate the form of the parts 3, 11, and 12 and the construction of the parts at the bottom of the loom. v

The ends of the weft-threads from the bobbins in the shuttle are led out through a vertical slot 7 in the side of the magazine 7 and attached at u or at some other convenient point. 1 Any means 'of attaching the threads may, however, be employed.

7 It will be understood that while we have described our invention as it is herein illustrated we do not limit ourselves to the exact construction shown,.as this may be varied to a considerable extentwithout departing from our invention. For example, the spring12 is only one form of spring that might be em- I f ployed for this purpose. There are also other known devices for holding up the shuttles in the magazine, and we do not limit ourselves to the means herein shown. Diiferent styles of looms, also, will require some modification I in the construction of the supply device, and

from the holder, but such degree of denudation as will permit the automatic devices in the shuttle to close the circuit.

Being the first, as we believe, to employ electrical means for controlling the weft-supply of a loom in a mechanism forautomatically supplying the weft or filling to the loom, we do not limit ourselves to specific means for this purpose, as such means may be varied almost indefinitely.

WVe have not shown in the figures all'of the various parts of the loom, but enough are shown to'illustrate the present invention.
